ABSTRACT:
A VCSEL for high power single mode operation and method of fabrication including a substrate element, a first stack of distributed Bragg reflectors disposed on a surface of the substrate element, an active region lattice matched to a surface of the first stack of distributed Bragg reflectors, and a second stack of distributed Bragg reflectors lattice matched to a surface of the active region. The VCSEL structure includes an isolation layer formed on the second stack of distributed Bragg reflectors. The isolation layer is formed of a dielectric material or insulating semiconductor material having an index of refraction greater than the first and second stacks of distributed Bragg reflectors and thereby defining an anti-guiding VCSEL structure. An electrical contact is coupled to a surface of the second stack of distributed Bragg reflectors and an electrical contact is positioned a surface of the substrate element.
